This invention more particularly relates to improvements in manually operated radiator shields or shutter frontsfor motor vehicles,

in which a supplemental shutter supporting frame is adapted for attachment to or removal from the engine radiator \YltllOlll) requiring constructive"changes in existingcars.

motor cars for distant actuating purposes! To this end and the accomplishment of otherncw and useful results, theinvention further consists in novel constructive"fea tures, combination andv arrangement of its several parts, all of which will be hereinafter more fully described and claimed.

Reference is, had to the accompanying one sheet of drawings which are illustrative of a specific embodiment of myinvention asapplied to. motor vehicles, in which likecharav ters of referenceindicate like. parts in the several views, and in which drawings: Fig. 1, is a vertical elevation in partial section showing a general arrangement of my shutter frame applied to the front face of an automobile radiator and also thehand operated actuating means therefor.

Fig. 2, is a fragmental enlarged vertical sectional detail taken through the upper portion of the assembled shutter frame-With the slats set in open position.

Fl 3, isa View similar to Fig. 2, but showing the shutter slats drawn into closed position. i

Fig. 3, represents atransverse fragmental section as taken on line 3-3, Fig. 3, to show theassembled t1e-bar which interconnects the shutter arms and serves to move the slats in unison.

Fig. 41 showsa sectional detail of the knob attached to the adjusting end of the shutter actuating linkage, hile Fig. 5, isa bottom view thereof.

Referring more particularly to said drawings, A, denotes a motor vehicle radiator tank or casing Which circulnscribes a honeycomb or other cellular core A said core of the usual flat type having opposite {front and rear faces provided With a plurality ofrather closely spaced horizontal openingsflthere- 'through in the conventional manner. shield or shutter frame 1spreferably mounted finsuch fashion that the perimeter ofits flared flat flange or brim Will lit againstthe front face of the core and substantially cover the plural core openingsso as to permit control ling the flow of cooling air through said core. My assembled, shutter frame housing t as such, is designated in its entirety by the letter Band is preferablymade up of sheet metal sections, comprising two parallelly disposed side-pieces having their respective ends cross 1 The W i connected by two similarly formed end-pieces such as 13 These sectional or component frame parts constitute an endless rectangular frame housing into which. j-arepivotally mounted a plurality of paralleldamperslats or shutters such as C C, etc. When closed,

the adjacent shutter edges overlap each other as shown 111 Fig. 3, and these stats may each be equipt with an actuating arm G and connected together to move in unison by thetiebar C Thetopmost of said slats may be provided With a set of rockerqlevers C to which is attached theshut-ter manipulating linkage which shown] as comprising a two part adjustable actuating rodmadeiupxof the sections 1),, and D Whilethe freeorrenlote end of this rod is'carrled up through the dash board D and lnay-be slidably supported by means of an escutcheonplate attached to the instrument board Dias indicated inFigLl.

.To the end that my shutter as attached to the front face of the radiator, may readily he fitted for. manipulation from the re: r thereto operate through a suitable radiator core levers C in an improved fashion. purpose, the complementary spaced rocker l r (1,, may he used and for sakeofobviatj 111;; separate iulcrumrneans therefor, such bracket is preferably attached to rock with the uppermost slat C, as shown.

The conr of, said actuating mum," is slidablvmountcd mon fulcrum axis of said levers is intended to align With the respective parallelslat pivots and between these levers ismounted an elongated pin C The aforesaid shutter actuating linkage may further comprise a relatively narrow link D whoseone eye may be shiftably fulcrumed upon the relatively long pin (1,, so as to allow of considerable lateral sliding movement. thereon. The other eye of" said link may be-made to engage with the hook end D bent up from the link end of the push 1 rod D, The push rod as a whole may be made in two overlapping parts, one being the link rod D and the other a knob rod D the respective sections being secured together by the adjusting clampD V I It is expedient to lace the control or knob end of the combiner push rod some distance above and away from the radiator and in present instance, this is accomplished by inking each of therods as shown in Fig. l

andbringing the two opposite rod 'ends back into substantial alignment. The inovement of the linkend of rod D may be constrained and made to slide through a suitable horizontal hole in the core A which is preferably reenforcedby the guide bush D thus protecting the adjacent core walls against I wear and causing the rod hook D to travel normal to the vertical front faceof radiator core. When the shutters are opened, the link D as shown inFig. 2, preferably assumes a position of substantial alignment with respect to its adjacent rod axis while when the s iutters are closed, the link is allowed to drop slightly as shown in Fig. 3. The swivel action on part of the link D allows of considerable vertical latitude in the selection of the most suitable core hole opening for mount ing the bush 1),, while the free lateral movement of the link onthe pin C further facilitates the finding of such a core hole as measured in a horizontal direction, thus affording universal freedom to rod alignment with respect to the encircling walls of the particular core aperture through which the rod slides.

In order to provide for properly holding the shutters in any desired intermediate posiclip resiliently bears down upon the rod D 7 For the purpose of changing the shutter ad justment, theknob is raised slightly against the clip thrust, which in turn disen 'ages the rod notch out of the Wedge D and permits the rod D, to be freely shifted into another notch position.

It is believed that the mode of operation of my shutter devices as applied to a radiator will readily be understood since its purpose and function has now become well known toautomobiie users, and itwill be obvious that the described actuating rod is intended torock all of the shutter slats in uni son. The use of my improvements makes it possible to fit any shape or size oi. radiator front for practically all leading makes of cars encountering undue difficulty in applying the described style of slat actuating device for rear control from the dash.

It will be understood that various chan es in the detailsand arrangement of my evices may be resorted, all without departing from the spirit andscope of my invention heretofore described and more particularly pointed out in the appended claims.

'Clairns: i

1. A shutter apparatus arranged to control air flow through an engine radiator core, comprisin a frame servingto house a plurality of siutter slats adapted to swing between open and closedpositions, tie-bar.

means interconnecting the several slats, slat actuating means includin" an elongated link pin operatively connected to rock inunison with the slat movements, said actuating means further comprising a reciprocative push rod having one end provided with an intermediary link adapted to pivotally engage and slide lengthwise of said pin, and guide means associated with said radiator core serving to constrain lateral movement on part of the link end of said rod.

2. A shutter apparatus arranged to con trol'air flow through a cellular engine radiator core, com rising a frame serving to house a plurality 0 shutter slats adapted to swing between open and closed positions, tie-bar means interconnecting the several slats, and slat actuating means including a link pin mounted upon one of said slats together with a reciprocative push rod extending through one of the core cells and of which rod one end is pivotally connected to said pin through the medium of a link.

In testimony whereof, I have herewith set my hand this 13th dayfof October, 1925.
